IntroductionCardiopulmonary resuscitation (CPR) guidelines throughout the world stress the importance of high quality chest compressions soon after cardiac arrest as the most significant factor in determining survival. Little evidence exists, internationally, documenting the quality of compressions provided by healthcare providers. In this study investigators sought to determine the quality of chest compressions delivered by rescuers. It was hypothesized that greater variably in compression quality exists between rescuers than variability in individual rescuers over time.MethodsIn this observational pilot study, basic life support (BLS) providers from prehospital and in-hospital settings were invited to participate in the investigation. Ten minutes of continuous chest compressions were recorded on the Resusci Anne and the Laerdal PC Skillreporting System. An adequate compression was defined as a compression with depth > 38mm, full chest recoil, and correct hand position. The Quality Compression Index (QCI) was developed to factor rate into the characteristics of an adequate compression. QCI is a scaled performance index calculated every 30 seconds.ResultsProviders came from a variety of clinical backgrounds, aged 35.5 ± 11.0 years. Of the 103 total participants, 94 (91.3%) completed 10 minutes of compressions. The most significant degradation in the quality of compressions occurred within the first two minutes. There was greater variability between different rescuers than the variability over time. Mean Square Error (MSE) due to subjects was comparatively greater than the MSE due to time (63.2 vs. 7.68). Performance of CPR, male sex, < 45 years of age, and prehospital background, correlated with higher quality. Time since last BLS certification and the number of times a rescuer completed a BLS class did not correlate with the quality.ConclusionsGreater variability in the quality of compressions exists between different rescuers than a rescuer over time. Some participants were not able to deliver ideal compressions from the start, when the effects of fatigue were minimal.

This brief report presents the global problem of the shortfall of donor corneal tissue for transplantation, a potential root cause (‘ick factor’ language), and a potential solution (modification of ‘ick factor’ language). Specifically, use of the term ‘eye donation’ is a potential hurdle to ocular tissue donation as it can stimulate the ‘ick factor.’ Verbiage such as ‘ocular (eye tissue)’ could be a method of providing terminology that is less emotive than ‘eye donor’ or ‘eye donation.’ The field of transplantation has experienced terminology shifts over time; for example, ‘cadaver’ has been replaced with ‘deceased donor,’ ‘harvest’ has been replaced with ‘recover,’ and ‘life support’ has been replaced with ‘ventilated.’ Notably, only a small number of regions worldwide are using ‘ocular’ terminology, yet it could be an important step to enhancing the informed consent process and improving donation rates, potentially increasing transplant and optimising patient quality of life for those with treatable blindness.

IntroductionIn conventional basic life support (c-BLS), a lone rescuer is recommended to start chest compressions (CCs) after activating the emergency medical system. To initiate earlier CCs in lone-rescuer BLS, we designed a modified BLS (m-BLS) sequence in which the lone rescuer commences one-handed CCs while calling for help using a handheld cellular phone with the other free hand. This study aimed to compare the quality of BLS between c-BLS and m-BLS.MethodsThis was a simulation study performed with a randomised cross-over controlled trial design. A total of 108 university students were finally enrolled. After training for both c-BLS and m-BLS, participants performed a 3-minute c-BLS or m-BLS on a manikin with a SkillReporter at random cross-over order. The paired mean difference with SE between c-BLS and m-BLS was assessed using paired t-test.ResultsThe m-BLS had reduced lag time before the initiation of CCs (with a mean estimated paired difference (SE) of −35.0 (90.4) s) (p<0.001). For CC, a significant increase in compression fraction and a higher number of CCs with correct depth were observed in m-BLS (with a mean estimated paired difference (SE) of 16.2% (0.6) and 26.9% (3.3), respectively) (all p<0.001). However, no significant paired difference was observed in the hand position, compression rate and interruption time. For ventilation, the mean tidal volumes did not differ. However, the number of breaths with correct tidal volume was higher in m-BLS than in c-BLS.ConclusionIn simulated lone-rescuer BLS, the m-BLS could deliver significantly earlier CCs than the c-BLS while maintaining high-quality cardiopulmonary resuscitation.

Introduction: Lack of resuscitation skills of nurses in basic life support (BLS) and advanced life support (ALS) has been identified as a contributing factor to poor outcomes of cardiac arrest victims.Objective: To assess the effectiveness of education intervention programme to improve the knowledge of, and thereby the quality of Emergency service; especially in the area of Basic Life Support, Advance Life Support and Triage system.Method: Pre-experimental research design was used to conduct the study among the nurses working in Emergency units of B. P. Koirala Institute of Health Sciences where CPR is very commonly performed. Using convenient sampling technique, a total of 24 nurses agreed to participate and to give consent were included in the study. The theoretical, demonstration and re-demonstration sessions were arranged, involving the trained doctors and nurses during the three hours educational programme. Post-test was carried out after education intervention programme. The 2010 BLS and ALS guidelines were used as guide for the study contents. The collected data were analyzed using SPSS-15 software.Result: It was found that there is significant increase in knowledge after education intervention in the components of life support measures (BLS/ALS) i.e. ratio of chest compression to ventilation in BLS (P= 0.001), correct sequence of CPR (p< 0.001), rate of chest compression in ALS (P= 0.001), the depth of chest compression in adult CPR (p< 0.001), and position of chest compression in CPR (P= 0.016). The participating nurses well appreciated the programme and requested to continue in future for all the nurses.Conclusion: The workshop certainly improves the knowledge of the working nurses, and thereby the quality of Emergency service; especially in the areas of Basic Life Support, Advance Life Support and Triage System.Journal of BP Koirala Institute of Health Sciences, Vol. 1, No. 1, 2018, page: 14-19

Background. The current basic life support guidelines recommend two-minute shifts for providing chest compressions when two rescuers are performing cardiopulmonary resuscitation. However, various studies have found that rescuer fatigue can occur within one minute, coupled with a decay in the quality of chest compressions. Our aim was to compare chest compression quality metrics and rescuer fatigue between alternating rescuers in performing one- and two-minute chest compressions. Methods. This prospective randomized cross-over study was conducted at Songklanagarind Hospital, Hat Yai, Songkhla, Thailand. We enrolled sixth-year medical students and residents and randomly grouped them into pairs to perform 8 minutes of chest compression, utilizing both the one-minute and two-minute scenarios on a manikin. The primary end points were chest compression depth and rate. The secondary end points included rescuers’ fatigue, respiratory rate, and heart rate. Results. One hundred four participants were recruited. Compared with participants in the two-minute group, participants in the one-minute group had significantly higher mean (standard deviation, SD) compression depth (mm) (45.8 (7.2) vs. 44.5 (7.1), P=0.01) but there was no difference in the mean (SD) rate (compressions per min) (116.1 (12.5) vs. 117.8 (12.4), P=0.08), respectively. The rescuers in the one-minute group had significantly less fatigue (P<0.001) and change in respiratory rate (P<0.001), but there was no difference in the change of heart rate (P=0.59) between the two groups. Conclusion. There were a significantly higher compression depth and lower rescuer fatigue in the 1-minute chest compression group compared with the 2-minute group. This trial is registered with TCTR20170823001.

Aim: Compare which resuscitation (for cardiac arrest scenario) has a higher quality when first responders with a duty of care are deprived of material: a standard resuscitation algorithm or a hands-only one when performed by lifeguards, who have had extensive training on mouth-to-mouth ventilation. Besides, a more specific objective was the analysis of the characteristics of these mouth-to-mouth ventilation. Methods: We conducted a prospective quasi-experimental crossover manikin study with clinical simulation with 41 lifeguards attached to the Plan of Surveillance and Rescue in Beaches. Each participant performed 2 minutes of basic life support (CPRb). Afterward, each participant performed 2 minutes of CPR with hands-only (CPRho). The data collection was carried out with a CPR calibrated Mannequin. Results: The mean depth was 48.05± 8.99 mm for CPRb, and 44.76 ± 9.73 mm for CPRho (t = 5.81, p < 0.001, 95% CI, 2.15 - 4.44), the rate was 123 ± 16.11 compressions/min for CPRb and 120 ± 17.89 for CPRho. The CPRho achieved a mean of 46 ± 42.6 complete chest recoil, versus 35 ± 35.19 for CPRb (z = -2.625, p = 0.009). 20.74% of ventilation were hypoventilation and 42.72% were hyperventilation. Conclusions: Mouth-to-mouth ventilation performed by lifeguards (without devices) was not effective. When ventilations were not performed, the number of high-quality compressions increased in absolute values. The mean depth of chest compressions was higher in the CPRho. Most of the participants did not perform the ventilations correctly, which resulted in time without compression and ventilation. The number of chest compressions with complete chest recoil was higher in CPRho. When ventilations were not performed, the number of high-quality compressions increased in absolute values.
